4.1.1
Settings on the case
1. Disconnect measuring case.
2. Set the transducers W1…4 for the Rogowski coils to the expected measuring
range using the DIP switches.
DIP switch
Use the DIP switches to set the conversion ratio of the Rogowski coils at the transducers.
Table 4.1: Table DIP switches for transducers
For "
Compensation
", the length of the used Rogowski coil is indicated in mm. The sup-
plied Rogowski coils must be set to 600.
3. All 8 jumper wires must be inserted in
position "Rogowski".
Changes to the DIP switches can only be carried out when the power
supply is
disconnected

1 = 4000 A
In the example, the range "630 A" is set.
2 = 2000 A
3 = 1500 A
4 = 1000 A
5 = 630 A
6 = 400 A
7 = 250 A
8 = 100 A
